Objective:
To assess parameters related to ligasure tonsillectomy (LT) versus cold knife tonsillectomy (CKT) procedure.
Study Design:
Prospective randomized study.
Methods:
A prospective study was conducted on 200 consecutive adult patients undergoing tonsillectomy. Indications included chronic tonsillitis and obstructive sleep apnea syndrome. Patients undergoing adenoidectomy, or any procedure together with tonsillectomy, and patients with peritonsillar abscess history or bleeding disorders were excluded. Patients were randomly assigned to either the LT or CKT group. Intraoperative bleeding, operative time, postoperative pain using a visual analogue scale, and complication rates were evaluated.
Results:
The LT and CDT groups consisted of 108 and 92 individuals, respectively. In the LT group, there was no measurable intraoperative bleeding, whereas mean bleeding for CKT group was 125 mL. The mean operative time was 15 +/- 1.43 minutes for the LT group and 21 +/- 1.09 minutes for the CKT group (P < .001). The overall mean pain score for the LT group was 3.63, whereas for the CKT group it was 5.09 (P < .001). Primary hemorrhage occurred in one subject of the CKT group. Secondary postoperative hemorrhage was noticed two subjects of the LT group and two subjects of the CKT group. In 21 subjects of the LT group, limited peritonsillar edema was noticed. No other complication occurred in both groups.
Conclusion:
LT procedure provides sufficient hemostasis, lower postoperative pain, and reduced operative time, as well as safety against Creutzfeld Jakob disease transmission.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
